Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache Pulsar Proxy (org.apache.pulsar:pulsar-proxy) versions 2.6.0 to 2.10.5, 2.11.0 to 2.11.2, 3.0.0 to 3.0.1, and 3.1.0 are affected. An attacker with network access to the proxy's /proxy-stats endpoint can, without authentication, view statistics about live connections, including client IP addresses, and change the logging level of proxied connections, which could cause denial of service through heavy logging. Upgrade to 2.10.6, 2.11.3, 3.0.2, 3.1.1, or later. The proxy is not intended for direct internet exposure, so restricting network access to it is also advisable.
